Windstorms are often a consequence of the passage of extratropical cyclones. Extratropical cyclones are synoptic-scale weather systems associated with low pressure that generally originate in the North Atlantic and progress northeasterly towards Europe. These systems can be characterised by paths of local vorticity maxima, which we refer to as tracks. Cyclones are typically formed as a result of horizontal temperature gradients and evolve according to a particular lifecycle with associated frontal systems [1]} where cold and warm air masses converge. High winds tend to occur along these boundaries [2]}. A large body of research exists on cyclone identification, storm tracking and feature extraction in reanalysis datasets [3]}, [4]}, which produce good approximations of how a track develops in space and time. The study of cyclones with respect to the cyclone centre, a Lagrangian frame of reference, has provided useful insight into the evolution of cyclones and the physical process that drive evolution [5]}, [6]}, [7]}. However, there has been little work on characterising the ensuing extreme winds in a robust way within such a framework.
